More recently, proposed methods involve enhancement of the SNR of the backscattered signal, resulting in high visibility by using high extinction ratio (ER) pulses which reduce the coherent noise [7].
Recently, an algorithm has been suggested [1] on the basis of the coherent noise model [2-4] and natural time [5-7] that might be useful for the determination of both magnitudes and occurrence times of aftershocks.

The EMC118X family employs frequency-hopping on the sampling frequency, which avoids the injection of coherent noise and enables traces of up to 8 inches while maintaining accurate temperature readings.
Frequency spectra and signal-to-noise (S/N) ratios were analysed for a number of combinations of sources and surfaces as well as properties of source generated coherent noise.
Using digital signal processing techniques automatic gain control, notch filter and band pass filter have been incorporated for initial processing of raw data to enhance the weak events from far offsets and suppress any coherent noise. The final record is saved in SEG-2 format.
introduced its AS8Y1100M30M/AS8C1150Z30M 0.8 [micro]m high power superluminescent diodes (SLDs) that feature high precision with low coherent noise, high resolution with wide spectral half width and sharp directivity.
"She had lost the ability to make a coherent noise, the treatment proceeded against her will and contrary to her best wishes."
Receiver arrays are used to attenuate undesired coherent noise in certain wave numbers.
